Title: Method of manufacturing a semiconductor device
Inventor: CZERNIAK MICHAEL ROGER
IPC: H01L21/365
Filed: 1984-09-19
Abstract: A method of manufacturing a semiconductor device, in which method a heterostructure of doped and/or undoped binary and/or ternary alloys of a II-VI ternary alloy system, e.g. Cd-Hg-Te, is grown epitaxially on a heated monocrystalline substrate (29) provided on a susceptor (5) in a reaction vessel (1). The reaction vessel contains a mercury source (2, 3), a supply of hydrogen and Et2Te is passed into the reaction vessel (1) through a tube (11), and a supply of hydrogen and Me2Cd is passed into the reaction vessel (1) through a tube (12) which ends in the reaction vessel (1) at a location between the mercury source (2, 3) and the substrate (29). The mercury source (2, 3) is heated so as to generate a partial pressure of mercury which is greater than the partial pressure of mercury generated by the mercury- containing alloy to be grown on the substrate (5). The substrate (5) is heated to such a temperature that the Et2Te and the Me2Cd decompose in the region of the substrate (5). A significant problem in growing heterostructures of alloys from the Cd-Hg-Te system is to produce heterostructure having narrow interfaces between the layers (30) and (32). After a first layer (30) has been grown on the substrate (5), the flow-rate of the hydrogen and Me2Cd passing through the tube (12) is abruptly changed by means of solenoid valves (21, 25, 22 and 28), the transit time of flow of the gas current from the valve (25 or 28) to the substrata 5 being less than 1 second. <IMAGE>

Title: Separation of hydrocarbon mixtures
Inventor: JONES DAVID ANDREW
IPC: F25J3/02
Filed: 1987-06-12
Abstract: In the process for the recovery of e.g. NGL or LPG and light gas from a gaseous hydrocarbon feed 11, it is found that where a large throughput is desired, a capital cost- and weight-effective alternative to the use of a refluxing heat exchanger involves cooling the feed gas in a heat exchanger 1 at superatmospheric pressure, rectifying the cooled feed gas, partially condensing product vapour recovered as overhead from the rectification column 2, returning condensate to the rectification column as reflux and recovering uncondensed vapour as light gas, and recovering the LPG or NGL as liquid bottoms from the rectification zone. The cooling of the feed gas is effected by indirect heat exchange with the light gas and the process also includes withdrawing vapour from the rectification zone at at least one point intermediate the feed and the overhead, cooling and partially condensing that vapour by indirect heat exchange with said light gas and returning the partially condensed fluid to the rectification at a point intermediate the withdrawal point and the overhead. An apparatus for carrying out the method is also described.   <IMAGE>
